It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-90372 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-90372/ (Markdown: https://insights.sbomify.com/CVE-2026-90372/index.md)","id":"CVE-2026-90372","markdown":"https://insights.sbomify.com/CVE-2026-90372/index.md","name":"CVE-2026-90372","record":{"aliases":["AZL-102381","BELL-CVE-2026-90372","DEBIAN-CVE-2026-90372","GHSA-934p-6j28-7ggx","UBUNTU-CVE-2026-90372"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel WiFi driver","requires_auth":"none","summary":"An integer underflow in the mt7915 WiFi driver can cause invalid beamforming data to be sent to firmware, potentially leading to system instability or denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7915: avoid nss underflow in mt7915_mcu_get_sta_nss\n\nIf a peer's VHT/HE MCS map has no supported spatial stream (all fields\n0x3), the loop exits with nss == 0 and the function returned (u8)-1 (255),\nwhich was then written into the firmware sta_rec_bf beamforming fields.\nClamp the result to 0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"wifi: mt76: mt7915: avoid nss underflow in mt7915_mcu_get_sta_nss","id":"CVE-2026-90372","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"wifi: mt76: mt7915: clear wcid mask under mutex after RCU pointer clear","id":"CVE-2026-90373"},"packages":[],"prev":{"headline":"wifi: mt76: fix RXDMAD_C buffer recycling race","id":"CVE-2026-90371"},"products":["Linux"],"published":"2026-09-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"An integer underflow in the mt7915 WiFi driver can cause invalid beamforming data to be sent to firmware, potentially leading to system instability or denial of service.","url":"https://insights.sbomify.com/CVE-2026-90372/"}
